Title: Improvements in or relating to number testing arrangements
IPC: H04M15/10
Filed: 1959-06-01
Abstract: 924,437. Circuits employing saturable magnetic elements; automatic exchange systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 1, 1959 [June 4, 1958], No. 18589/59. Classes 40 (4) and 40 (9). A translator provides one of three outputs to indicate to which of three groups any applied sequence of three digits belongs. The translator comprises three rows of saturable cores K 11 , K 12 ; K 21  to K 23 ; and K 31  to K 34 . As each digit is received its value is set up on a switch CS to select a code wire threading the cores in a pattern depending on the membership of each number group. For the first, second and third digits a switch PS connects a pulse source A to the first, second and third row wires L 1 , L 2 , L 3  respectively. The row wires are connected in common to the wiper of the digit value switch CS. A common wire T threads all the cores and with a switch TS switches the first row to P states and the other rows to N states. Each core has an output circuit with a rectifier G and capacitor C which is energized when its associated core is switched from P to N state and switches to P state a core in an inferior row or one of the three cores KA, KB or KC which record whether a number is group A, B or C. For any incoming digit a row wire and a code wire are pulsed in the same circuit with a half-write pulse. Where the row wire and code wire thread the same core, the core is switched to the N state. If the first digit is 1, 3, 4, 5, 6 or 8, core K 11  is switched and sets core KC to indicate a number in group C. Subsequent drive to the second and third rows is ineffective as the cores are in the N state initially. The only other significant first digit is 2 which switches core K 12  to the N state, causing its shift circuit to set cores K 21  to K 23  of the second row to their P states. If the second digit is 2, core K 21  is switched to set core KC indicating that 220 to 229 are members of group C. The only remaining significant second digits are 5 and 9. If the second digit is 5 core K 22  is switched to the N state to drive cores K 31  and K 32  to the P state. If the third digit is then 3 core K 32  reverts to the N state and sets KC to indicate that 253 is in group C. If the third digit is 0, 1, 2, 4, 5 or 6, core K 31  turns back to the N state and core KB is set to indicate 250 to 256, except 253, as members of group B. If the second digit is 9, core K 23  switches in the second row and sets cores K 33  and K 34  in the third row. Cores K 33  and K 34  now distinguish between third digits 0 or 6 and digits 4, 5, 7, 8 or 9 to indicate membership of group A or B by switching cores KA or KB. The switches PS and CS may be rotary selector switches or may be relay, valve, or transistor circuits capable of performing the same function.

Title: Improvements in and connected with machines for hammering piston rings
IPC: B23P9/04
Filed: 1930-06-19
Abstract: 347,054. Hammering piston-rings. BROADBENT, T. and CARSON & CO., Ltd., J., Fawley Road, Tottenham Hale, London. June 19,1930, No. 18678. [Classes 83 (ii), 83 (iii), and 83 (iv).] Chucks.-In a piston-ring hammering machine of the kind wherein the ring is mounted in a stepwise rotating holder and hammered on the inside by a striker reciprocated in the space inside the ring which is rotated through distances progressively diminishing so that the blows are closer together at the portion of the ring opposite the split part, the housing 5 supporting the ring-shaped holder 7 for the piston ring 6 is rotated intermittently by a uni-directional feed member 28 connected by a rod 27 to a block 40 reciprocated in a guide 41 by a rocking lever 26, the guide 41 and block 40 being moved automatically towards and away from the axis of the rocking-lever to vary the feed movement. The piston ring 6 is fixed in the holder 7 by pins 9 adjustable in slots 9a in a plate 10 mounted on a bolt 12 carried by an arm 13 pivoted at 14 to the housing 5, a spring 16 around the bolt 12 pressing the pins 9 up against the piston ring. The hammering chisel 17 is mounted on a slide 22 lifted by a cam 23 and delivers its blow by gravity or by the pressure of a spring 55 adjusted by a screwed sleeve 56. The housing 5 has a flange 30 engaged by pins 29 on the feed member 28 which is weighted at 28a so that the reciprocation of the rod 27 drives the housing in one direction only ; movement in the reverse direction is prevented by pins 35 on a holding member 31 weighted at 31a and slotted at 32 to engage a rotatable block 33 on a fixed pin 34. The rocking lever 26 is actuated from the shaft 2 by a crank 24 and link 25, and the feed variation is effected by a cam ring 43 on the housing 5 engaging a nose 44a on a finger 44 on a rockshaft 45 carrying a segment 46 engaging a pinion 47 on a shaft 48 carrying a second pinion 49 gearing with a rack 50 which moves the guide 41 towards and away from the axis 36 of rocking lever 26. The block 40 has a projecting pin 39 engaging a block 38 working in a slot 37 in the rocking lever. A projection 57 on the housing coacts with a lever 57a to stop the machine when the hammering is completed. The hammer is held out of action from the parts of the piston-ring adjacent the gap by a segment 52 on the housing engaging a roller 53 on the hammer slide 22. In a modification of the feed device, Fig. 5, the pins 29 of the feed arm 62 are held in contact with the housing rim 30 by a spring 63, the arm 62 being steadied by a depending rod 64 engaging the frame of the machine at its lower end.

Title: Control rods for nuclear reactors
Inventor: BELL FRANCIS ROBERT
IPC: G21C7/20
Filed: 1959-06-01
Abstract: 915,807. Energy-absorbing devices. DE HAVILLAND ENGINE CO. Ltd. May 24, 1960 [June 1, 1959], No. 18689/59. Class 103 (1). [Also in Group XL (a)] A control rod-support tube 12 above the core 13 of a reactor carries friction brakes such as cams 17 which are normally out of contact with the control rod 11 but make contact with a braking surface on the rod as the rod approaches the bottom of its travel, the tube being capable of deflection to allow the brake to accommodate the braking surface; the tube shown is split longitudinally in a plane perpendicular to that of the drawing to accommodate neutron - absorbing plates on the rod and to allow deflection. The arrangement retards the rod after it reaches its position of greatest effect on being dropped into the core. The cams are so shaped that they do not greatly impede lifting of the rod. The contact surfaces of the cams may be of tungsten carbide. Specification 915,808 is referred to.

Title: Improvements in or relating to control systems for electric lift motors
IPC: B66B1/16
Filed: 1957-06-13
Abstract: 862,954. Control of motors; controllers. SCHWEIZERISCHE WAGONSUND AUFZUGEFABRIK AKTIENGESELLSCHAFT SCHLIEREN-ZURICH. June 13, 1957 [June 14, 1956; Dec. 5, 1956], No. 18753/57. Class 38 (3). When a holding brake 14 is removed, an induction motor 1 is connected to source 31 through contactor 32, a contactor 33 being closed to connect inverter 34 to rectifier 35. The voltage developed across capacitor 38, when contact 37 opens, serves as a reference voltage with which the voltage of tachometer generator 5 is compared, the error voltage being applied to the grid of triode 42. This enables triode 49 to control the energization of the winding 36 of a saturable reactor thereby regulating the current flowing between rectifier 35 and inverter 34, so that lift-car 2 is driven in accordance with a predetermined acceleration programme. When full speed is reached, the error signal controlling the triode 42 increases rapidly and relay 52 closes contacts 54 to shortcircuit the rotor of the motor. When the car 2 approaches a desired stopping-position, switch 8 engages clutch 6, and potentiometer 7 provides a decreasing reference voltage for the deceleration programme. The capacitor 38 is discharged and the relay 52 is de-energized. When a voltage derived from the potentiometer 7 equals a voltage from the tachometer generator 5, triode 48 energizes relay 12 to provide directcurrent braking of the motor under the control of winding 36. If the switch 8 is actuated before full speed is reached (for short runs of the lift car) the acceleration programme is continued until the voltages derived from the potentiometer 7 and generator 5 are equal, so effecting a smooth change-over from driving to braking. The potentiometer 7 may be replaced by a cam-operated differential transformer, Fig. 2 (not shown).

Abstract: 718,152. Horse and like clippers. TEXTILE TRIMMING & BOARDING MACHINE CO. July 25, 1952, No. 18884/52. Class 131 [Also in Group VIII] A textile clipping machine comprises a trimming device including suction means, cutting means, and thread directing means mounted in predetermined relation to the cutting means, the device being movable relatively to the fibre to be trimmed and the thread directing means being positioned and adapted to cause, in co-operation with the suction means, substantially normal positioning of the loose threads on the fabric in front of the cutting means prior to their severance by the cutting means. As shown, the clipping head of a clipping machine such as that described in U.S.A. Specification 2,113,112 is fitted with a nosepiece A fixed to a cut-away portion 17 at the front of suction nozzle B by means of an anchorage flange 18 and screws 20. A pair of supporting members 26 project rearwardly from flange 18 and the space between members 26 is divided by parallel guide members 26A to provide guide grooves 27. Members 26A are shorter than members 26 so that a gap 24 is left between the ends of members 26A and the tips of the cutting blades 12, 13, into which gap loose threads are raised prior to cutting. During operation, nose-piece A supports the nozzle on the fabric being trimmed. For controlling the length of the clipped threads, the nosepiece is vertically adjustable by means of slots 19 therein through which the anchoring screws 20 pass. Provision may be made for screw adjustment of guide members such as 26A towards or away from the cutting blades to vary the width of gap 24 in accordance with the type of thread to be clipped. The width of grooves 27 may be determined according to the weight of the fabric to be trimmed; for very heavy and stiff material guide members 26A may be dispensed with altogether. A number of alternative constructions of nose-piece are described.

Title: Doll's limb
IPC: A63H3/46
Filed: 1969-04-14
Abstract: 1,267,831. Doll's limb. SCHILDKROT A.G. 14 April, 1969 [18 April, 1968], No. 19058/69. Heading A6S. Knee and elbow joints for dolls limbs are shown in the figure. Each limb comprises an upper and lower portion, e.g. an upper arm 1 and forearm 4 interconnected by a joint 10. The arm is assembled from elements 2, 3, 5 and 6, the elements 2 and 3 being joined together along their abutting edges 7 and the elements 5 and 6 along their abutting edges 8. The plane containing the edges 7 or 8 of the elements intersects the axis 9 of the joint. The joint consists of two members each being formed rigidly with only one element. One member 11 is a centering member having a tapered blind hole and the other member 12 is a conical joint pin fitting into the centering member 11, there being sufficient friction between the two members to hold the joint in any desired position. The joint members are parts of opposite elements and each one of the elements 5 or 6 carrying the joint member is spherical in the region of the joint. The other element 5 or 2, the plane edge of which is not closed, engages over the spherical portions 13 and 14 as in the manner of a ball joint. The edges 15 or 16 are rotation symmetrical in the same manner as with reference to the same axis, so that in each position of the arm only the smallest possible gap remains between the outer face of the portion 13 and the edge 15 or between the portion 14 and the edge 16. When the elements 6 and 5 are joined together the forearm thus formed can no longer be drawn off in the direction of the axis 9, i.e. towards the doll's body. The arm is thus assembled by fitting together the members 11 and 12, i.e. elements 3 and 6. Then the two further partial elements 2 and 5 are stuck on so that the joint members are nondetachable.
